Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482966, here are decompositions:

19 + 31482947 = 31482966
59 + 31482907 = 31482966
107 + 31482859 = 31482966
127 + 31482839 = 31482966
167 + 31482799 = 31482966
223 + 31482743 = 31482966
257 + 31482709 = 31482966
283 + 31482683 = 31482966

Showing the first eight; more decompositions exist.
